Question about M2 Drives and SATA Bandwith

[seangrogan]

Looking for clarification on what the specs of the ASUS ROG STRIX Z270G GAMING says:

I want to stick an samsung 960 ssd in one of the m2 sockets. I believe one of the slots is behind the motherboard and that's where I plan on putting the 960 (i.e. i don't think it's effected by the problem). I would like to populate all the 6 SATA 6gbs ports as well.

The M.2_1 socket shares bandwidth with SATA_1 port when using M.2 SATA mode device. Adjust BIOS settings to use SATA device.

 

since the 960 is technically a PCIE, does that mean the bandwidth will be shared even if I plug it into the M2_1 slot? can I use a 960 in either (or both) as well as all the sata ports and be okay (no bandwidth loss?)?
thanks

I think it means that if you use the M.2 slot, it disables the SATA port. As is usually the case with ATX boards that have a full compliment of SATA ports and M.2 slots.

you can just buy a pcie card to get more sata ports
